While I disagree with a couple of the author's interpretations, this is a great book. It helps reinforce that there were people there. That Auschwitz was a place full of people. Sometimes the death that shrouds the Holocaust and the large numbers of the dead make it easy to forget that these were/are individuals. People. Not just prisoners, victims, Nazis, etc. The place was populated with people. To me, that's where it all becomes the most terrible. Read the book. Appropriate for most ages & would also be a good tool for parents trying to explain the Holocaust to kids. Includes many stories about the resistance movement there also.
